It *is* how we want to do microcode in the future. There is a prototype for the Intel hardware side here; we just haven't had time to finalize it partly because I got pulled onto the kernel.org situation.

But for right now, this patch seems like the pragmatic solution.

No.

I think the real question is where there's something objectionable about
the patch itself?

"It does something that is slightly broken on real hardware and totally broken for a hypervisor and perpetuates it, while still needing enabling?"
